<p>Flat slabs are popular among architects and clients due to their aesthetic appeal and economic benefits. Shear walls have grown in popularity due to their strong lateral load resistance. Shear walls may be created discontinuously in some structures due to architectural requirements or economic considerations. However, shear walls are often discontinued in the upper stories, where the story shear is smaller. The research objective is to assess seismic performance by comparing the flat slabs with continuous and discontinuous shear wall structural systems modeled with layered shell elements and thin shell elements. Commercial cum residential frame-shear wall-flat plate dual systems having three types of lateral system configurations with 10, 15, and 20 storied were considered for Seismic zone 2 as per BNBC 2020. For nonlinear static analysis, lateral load consistent with the mode shapes and hinge parameters as per ASCE 41-13 were used. From the results of linear static analyses, no soft story mechanism was developed for the discontinuity of shear walls for the considered models. However, maximum top displacement has increased significantly for the flat slab of layered shell models with discontinuous shear walls compared to continuous shear walls. From this study, it has been found that the R-value of a flat slab with a discontinuous shear wall structure is lower than that of a continuous shear wall structure. In addition, the response modification factor value reduces as the structure height increases.</p>
